  1. 1. On the Use of Rotational CARS on Polyatomics and in Time Domain

    Author : Ali Hosseinnia; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rotational CARS; Laser Diagnostics; Ethylene; Ethane; Internal Rotation; Coherent Lifetime; ultrafast spectroscopy; Fysicumarkivet A:2020:Hosseinnia;

    Abstract : This thesis work concerns the further developments of dual-broadband rotational coherent anti-Stokes Raman spectroscopy (RCARS) through experimental and theoretical investigations. Rotational CARS is an established technique for gas-phase thermometry and concentration measurement with major applications in combustion diagnostics. READ MORE

  2. 2. High-Sensitivity High-Resolution Diode Laser Spectroscopy in the Near-Infrared Region

    Author : Viacheslav G. Avetisov; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:1996:Avetisov;

    Abstract : High-resolution spectroscopy measurements have been performed using near-infrared diode lasers. Special emphasis was placed upon high accuracy absorption lineshape measurements, which provide the basis for quantitative gas analysis. For this purpose, relevant spectral characteristics of the radiation emitted by diode lasers were studied. READ MORE

  3. 3. Towards Single-Ion Detection and Single-Photon Storage in Rare-Earth-Ion-Doped Crystals

    Author : Mohammed Alqedra; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Single-ion detection; microcavities; quantum memory; rare-earth-ion-doped crystals; Fysicumarkivet A:2022:Alqedra;

    Abstract : Solid materials doped with rare-earth ions are considered an attractive platform for quantum information applications. One of the main reasons for this is the exceptionally long optical and hyperfine coherence times of the 4fn states, due to the shielding provided by the outer lying 5s and 5p electrons. READ MORE
